Looking at the picture, and having completed this step no more than 5 minutes ago, check there are at least 1 full thread sticking thru the nuts on the front and rear center section spar bolts. It is not clear in your picture, but I had to use an AN960- 10L washer on these, instead of the AN960-10 washer( the thicker version)

Not at this stage yet, but when I built, I machined some hard Delrin spacers for the spar carrythrough before I riveted it to the fuselage structure. In my opinion Vans instructions are poor here (I think they mention a wood block). The spacing should have a machined spacer and I think Vans should supply it.

However, this doesn't help you. This also happened to a friend of mine, and Vans recommended de-riveting the skin overlap on the bottom of the fuselage, insert the spars (or machined spacers would probably work)and re-rivet the skin overlap.
